SPECIFICATION forming part of Letters Patent No. 669,002, dated February26, 1901.

Application filed June 27, 1900.

To all whom it may concern:

Be it known that LGUSTAVE ROUY, a citizen of the United States, residingat El Paso, in the county of El Paso and State of Texas, have inventednew and useful Improvements in Car-Trucks, of which the following is aspecification.

My invention relates to trucks for railwaycars; and its objects are toprovide a truckframe of simple and durable construction the parts ofwhich are connected together without the use of bolts, to provide anindependent axial support for each of the wheels of the truck, toprovide a spring-bolster and means for supporting the same, andgenerally to simplify and improve the construction of railwaytrucks.

The invention is especially adapted for use in connection with therailway brake disclosed in Letters Patent No. 530,460, granted to meunder date of December 4, 1894, and I have shown in the drawings whichaccompany this specification a part of the brake mechanism covered bythe Letters Patent above referred to.

The construction of the present improvements will be fully describedhereinafter, and described in the appended claims, in connection withthe drawings, in which- Figure 1 is a side elevation of a truckembodying the invention. Fig. 2 is an end elevation of the same. Fig. 3is a horizontal section of the truck, and Fig. 4 is a transversevertical section of the same.

The frame of the truck comprises parallel longitudinal beams 1 and 2,arranged in pairs and constituting the sides of the frame, andtransverse beams 3 and 4. The outer side beams 2 are formed at theirends with recesses 5 to receive lugs or tongues 6, formed on the ends ofthe cross-beams 3 and 4, and the ends 7 of the inner side beams 1 extendthrough openings 8, formed in the crossbeams 3 and 4, adjacent to theends thereof. The ends of the several beams are secured in theirassembled positions by vertical pins 9, which extend through suitableopenings formed in the beams, as illustrated in Figs. 2 and 3, and bythis construction I avoid the use of bolts for securing the parts of theframe together and the consequent annoy- Serial No. 21,838. (No model.)

ance and danger incident to the loss or loosening of securing-nutsemployed with bolts.

The side beams 1 and 2 are centrally recessed to form seats 10, uponwhich are supported plates 11, having recesses 12 on their upper facesto receive the lower ends of the coil-springs 13, the upper ends ofwhich are supported in recesses formed on the under surfaces of the endsof a bolster 14. This bolster 14 forms a yielding support for the centerbearing of the car.

15 and 16 designate cross-braces having their ends 17 projectingupwardly at right angles and formed with openings which register withopenings 18 in the side beams 1 and 2 to form bearings for short axles19, one for each wheel 20. The inner ends of the axles 19 are secured onthe inner sides of the arms 17 by pins 21.

The wheels 20, as clearly illustrated in the drawings, are mounted upontheaxles 19 between the side plates 1 and 2 and are provided withroller-bearings 22, which are interposed between the axles and thecentral hub-opening of the wheels.

The cross-braces 16 serve not only to brace the frame transversely andto connect the inner side beams 1, but also as supports for the brakemechanism, comprising vertical shafts 23, brake-beams 24, carrying theshoes 25, and the levers 26. Inasmuch as the brake mechanism forms nopart of the present invention and is fully set forth in the LettersPatent above referred to, a detailed description of said mechanism isnot required.

An important result of the construction above described is that when myimproved brake-is applied thereto the braking action is more direct andimmediate, for the reason that the momentum of the short independentaxles 19 is much less than it would be if said axles extended entirelyacross the truck. Again, the construction shown avoids the dangersincident to the breakage of axles, the roller-bearings avoid hot boxes,and the parts of the truck-frame may be readily assembled, thuspermitting the renewal of any parts when required.

I claim- 1. A car-truck frame comprising parallel side beams arranged inpairs, and transverse end beams connected to the side beams, incombination with transverse braces secured to the inner side beams andserving as the supports for brake mechanism.

2. The combination with a car-truck frame, comprising parallel sidebeams arranged in pairs, and transverse end beams connected to the sidebeams; of transverse brace-bars having their ends projected upward andsecured to the inner side beams; axles projecting through openings inthe side beams and the upwardlyextending ends of the bracebars, andterminating slightly beyond said arms; and wheels mounted on said axles.

3. The combination witha car-truck frame, comprising parallel side beamsarranged in pairs, the outer beam of each pair being recessed at itsends, and transverse end beams formed with tongues fitting the recessesin the outer side beams and with openings through which the ends of theinner side beams extend; of short axles mounted independently inbearings formed in the side beams and secured at their inner ends bypins or keys; and wheels mounted on said axles between the outer andinner side beams.

4. The combination with a oar-truck frame, comprising parallel beamsarranged in pairs forming the sides of the frame, and transverse endbeams secured to the ends of the side beams; of wheels mounted each uponan independent axle supported in the bearings of the side beams;transverse brace-bars having their ends projected upward at right anglesand formed with openings through which the inner ends of the independentaxles extend; pins or keys for securing the axles; and brake mechanismsupported on said transverse brace-bar.

In testimony whereof I affiX my signature in presence of two witnesses.

GUSTAVE ROUY.
